In the public perception, the search for a repository for high-level radioactive waste is dominated by the coverage on the Commission "storage of high-level radioactive waste" which should prepare a site selection process by mid-2016. During the work of the so called “Repository Commission”, research in the field of disposal meanwhile has not stopped. Numerous other projects, some of them presented and discussed in this focus session, illuminate the various aspects related to final disposal and site selection processes and provide an important basis for the start of the new German site selection process.

This session will be held in German with simultaneous English translation.

Decommissioning of nuclear power plants is state of the art in a lot of countries. International guidance in case of safety standards is given from the International Atom Energy Agency, the safety guide for decommissioning of nuclear power plants, research reactors and other nuclear fuel cycle facilities will be finalized in 2016 and be presented as introduction of the session. Depending on national boundary conditions decommissioning strategies varies from country to country. Additionally countries are in different stages in performing decommissioning activities. The international survey applies to projects in USA, Spain, Switzerland and Germany. While Switzerland is in the planning phase, USA, Spain and Germany have already ongoing decommissioning projects.

There were many challenges coming from the different decommissioning projects in Germany as soon as they gathered pace. Industry has turned out resourceful and innovative though dealing with that challenges as they appear. This section shows innovative products and business schemes to deal with the decommissioning and waste management challenges on a daily basis.

This session will be held in German with simultaneous English translation.

The management of spent fuel assemblies from nuclear power plants so far has been mainly oriented towards the requirements of the various forms of interim storage due to a lack of appropriate final repositories. While the status “free from nuclear fuel” is an important precondition for the actual dismantling of already or soon to be shut down nuclear power plants, a thoroughly elaborated and comprehensive disposal chain can provide a sustainable contribution to a safe and economic operation of the globally planned new build projects in the long run as well as to the power plants running for an extended life‐time. During this Topical Session the various approaches and objectives in different countries shall be examined as well as new technical concepts and regulatory frameworks.
